190128 red admiral

The sun may have been shining but it was frosty and very chilly when I spotted this Red admiral on the Penarth to Lavernock coastal path this morning. This is actually my second Red admiral for the year – I also saw one at Cathays Cemetery in Cardiff last week, but only managed a photo of a blurry red splotch high in a tree. I couldn’t help but feel sorry for this morning’s little butterfly, partly because of the cold – and it’s forecast to get much colder in the coming week – but also because there were no flowers to be seen anywhere today. If it doesn’t freeze to death, this little Red admiral might well die of hunger.

Friday’s walk 3: a Clouded yellow!

Having enjoyed some wonderful bird sightings on Sully beach, I walked on along the Wales coastal path, through Swanbridge and past St Mary’s Well Bay to Lavernock. This lovely nature reserve, perched high on the cliffs above some of south Wales’s most dramatic coastline, is the best place I know to see butterflies over the spring and summer months.

However, this was late September and there was a cool wind blowing so, although the Devil’s-bit scabious was still flowering, I didn’t really expect to see many butterflies this day. How wrong I was! Not only did I see three Small coppers, a couple of Red admirals, a Painted lady and a Common blue, as well numerous Small whites and Speckled woods, I was absolutely delighted to spot this glorious Clouded yellow, a butterfly we don’t see very often in this neck of the woods.

Butterflies 2018

The sharp-eyed amongst you may have noticed that I recently added a new page to this blog (see the link in the top menu). As it says on the page, Butterflies 2018 is a chronological list of the first time I’ve spotted each British butterfly species during 2018. This isn’t like my Birding 2018 challenge, where I’m deliberately trying to see 200 species in a single year – 2018 just happens to have been a very good year for me for seeing more butterfly species than ever before (bear in mind that I’ve only been living in Britain three years, so I haven’t had a lifetime of butterfly watching, and there are plenty more species I’ve not yet seen). And I figured it would be a good idea to have a chronological list as a personal aide-memoire, so I know which butterflies to look out for in which months in future years.

Common it may be, but I still think the Common blue is one of Britain’s loveliest butterflies.

Holly blues, the second generation

I blogged about the Holly blue butterfly (Celastrina argiolus) back in May but I’ve since read some really interesting info about this lovely little butterfly and have some new photos to share as well.

180822 Holly blue (2)

My information comes from the book I’m currently reading, which I highly recommend – it’s Wonderland: A year of Britain’s wildlife day by day by Brett Westwood and Stephen Moss. The entry from 13 August is about the Holly blue and answered a query I had about why I’ve recently been seeing so many Holly blues on Ivy plants rather than on Holly.

180822 Holly blue female

It turns out the Holly blue has two generations per year: as their name suggests, the females from the first generation lay their eggs on Holly plants and that’s what the first generation of caterpillars munch on. Then, once those caterpillars have pupated, they emerge as butterflies from around mid July, and the females from that second generation lay their eggs on Ivy, as that’s what the second generation caterpillars eat.

I’ve also been wondering why I seem to be seeing so many more Holly blues this year and Wonderland has the answer to that too:

These fluctuations [in population], over a cycle of five or six years or so, are caused by a small parasitic wasp called Listrodomus, which injects the caterpillars with a long sting-like ovipositor. The Listrodomus grub lives inside the caterpillar, but keeps it alive long enough to allow it to pupate, emerging later from the chrysalis. As wasp populations increase, they reduce the Holly blues. Fewer butterflies mean fewer opportunities for the wasps and so, in turn, wasp numbers fall too. This allows the butterflies to build up again, and that’s why over a span of several years our sightings of Holly blues go up and down.

The quickness of the wing

‘The quickness of the wing deceives the eye.’ So write Brett Westwood and Stephen Moss in their brilliant book Wonderland: A year of Britain’s wildlife day by day (John Murray, London, 2017). They’re describing those butterflies that ‘fly so haphazardly and so fast that they are little more than hallucinations, a flicker of motion at the edge of our vision, making us question whether we’ve seen one at all.’

The Small copper (Lycaena phlaeas) is one such butterfly but, I find, with a pinch of stealth, a sprinkle of luck and a tablespoonful of patience, it will settle and even pose for photos. And the outcome is no hallucination but rather a delicious creation, even a gourmet would admire.

Two more lovelies

As I mentioned in yesterday’s post, last Sunday’s birding didn’t only produce some nice bird sightings, it also featured an abundance of beautiful butterflies, including two newbies for me.

I’ve been keeping an eye out for Clouded yellows (Colias croceus) for a couple of months now, as these immigrants can fly in from the southern parts of Europe and even north Africa as early as June. The occasional sighting has been reported in my area, with one being seen at Lavernock as recently as last Friday, but I hadn’t managed to spot one myself … until last Sunday.

180808 clouded yellows (3)

Ace birder Gareth spotted the first as we walked along the coastal path at Rumney Great Wharf, on the eastern side of Cardiff, and then a second was spotted soon afterwards. And then, as we retraced our steps back to the starting point of our walk, I spied two more, obviously a male and female engaged in their pre-mating aerial display. Luckily, their focus on mating meant I was able to get some open-wing photos, which, though not particularly sharp, are quite difficult with this butterfly, as it usually zooms along at quite a rate of knots.

180808 wall (1)

The second butterfly, which was again spotted by Gareth, was a first-ever sighting for me. This is a Wall (Lasiommata megera, until recently called a Wall brown), so named because of its liking for sunning itself on rocks, banks and, you guessed it, walls (though this one was not living up to its name!).

This particular Wall had been in the wars and was missing half of one wing and a third of the other, but was still flying well enough. I’m not sure I would have spotted it myself as, in flight, it looked very much like a small Meadow brown or a Gatekeeper, so I’m particularly grateful for Gareth’s sharp eyes.

I’ve had a fabulous summer of butterfly sightings, with my species total now on 34, but will these two be the final two species I see for 2018? Only time will tell.

The Painted Ladies

A google search on “Painted Ladies” will take you to San Francisco, as this is the name used by Americans to describe the local Victorian and Edwardian buildings, particularly houses, that have been repainted in multiple colours to highlight the details of their architectural style.

Britain’s Painted ladies have also been painted in multiple colours but not by human hands – these are the masterpieces of Mother Nature.

And they are not static – they fly, and not just around our local meadows and gardens – these beauties fly all the way from North Africa and the Middle East to dazzle us with their kaleidoscope of colour.

180806 painted lady (4)

Some years – 2009 was one – these butterflies arrive in huge numbers – and I do mean huge. That summer, tens of millions of Painted ladies arrived in Britain and the skies were filled with fluttering colour. I hope I live to see such a sight.

The flower of the moment is …

The flower of the moment is Fleabane (Pulicaria dysenterica) or, at least it is at Lavernock Nature Reserve.

180803 fleabane

I’ve read that Fleabane usually grows in ditches and damp meadows so, despite the recent drought conditions, I guess there must be water somewhere below the wildflower meadows at Lavernock, as they are currently awash with these bright golden flowers. And, at a time when most other wildflowers have dried up and died off, the Fleabane is providing a much-needed source of pollen and nectar for butterflies and other assorted mini-beasties.

Birding at RSPB Dungeness

I had never been to RSPB Dungeness until my visit with my friend Jill two weeks ago but, if you can get past the fact that there’s a nuclear power station buzzing away just down the road, then you should be able to appreciate what a wonderful place it is. (British people seem to take nuclear power stations for granted but, as a nuclear-free New Zealander, I still find them quite scary places and really rather menacing!)

180731 Dungeness nuclear power station180731 RSPB Dungeness

This is a unique landscape of low rolling shingle banks, interspersed with patchy areas of low scrub and large shallow pools – it’s water bird heaven!

180731 Common terns (3)

Our first highlight was seeing the Common terns that breed at Dungeness. Terns are such agile flyers and to see their young fledglings was a real treat.

180731 Egyptian geese

Eqyptian geese have also bred here, and we saw a pair with two well-grown goslings.

180731 snipe

I had my best-ever views of a Snipe that decided to come out and poke around the muddy edges of one of the pools. These are normally such secretive birds so it was a real pleasure to watch this bird foraging.

180731 wood sandpiper

And the Snipe was joined by not one but two Wood sandpipers.

180731 water birds galore

Each of the six hides on the two-mile-long main trail offers different views, different birds, and, after motoring down to a cafe near the lighthouse (and that power station), we also stopped off on our return to check out the two shorter trails and hides on the opposite side of the road. Here we had good, though distant views of a Greenshank and a Bar-tailed godwit. Cracking!

As well as the birds, the wildflowers added lots of pretty colour to our wander, and we were entertained as we walked by large numbers of beautiful butterflies and debonaire dragonflies, though it wasn’t quite so pleasant watching an Emperor dragon biting the wings off a Gatekeeper.

Here’s my bird list for the day (not including a lot of smaller birds that were flitting about the bushes while I was marvelling at the butterflies): Teal, Lesser black-backed gull, Tufted duck, Mallard, Herring gull, Common tern (with young), Cormorant, Sandwich tern, Common sandpiper, Wood sandpiper (2), Snipe, Egyptian goose (and goslings), Ringed plover, Pochard, Little grebe, Great crested grebe, Lapwing,Coot, Dunlin, Goldeneye, Reed warbler, Redshank, Woodpigeon, Oystercatcher, Grey heron, Great white egret (2), Greylag goose, Mute swan, Black-headed gull, Shelduck, Shoveler, Carrion crow, Swallow, House martin, Greenshank, Bar-tailed godwit, Pied wagtail, Gadwall and Magpie.
